The Route Selection Research Of Urban Recreational Greenways In Main Urban Area Of Harbin

Urban recreational greenways,as a kind of linear landscape space,dominated by recreational function connects the main city parks,scenic areas,nature reserves,historical and cultural areas,is a wide open space for city dwellers to enter.In the city,it plays both the function of garden space and the function of transportation,recreation and connection,and has received wide attention both at home and abroad.Harbin as the important center city in northeast China in our country,it is not a complete green road and recreation type green system planning,at the same time as the highest level of urbanization,population density,the lack of open space in the urban area and largest demand on construction of urban leisure type green way is the most urgent.Based on the above background,this paper studies the selection of green road in the main city of Harbin city.At first,this paper analyzes the domestic and foreign literature of greenway,and then combs out the research content of the urban recreational greenway route selection.Then,it clarifies the related concepts of the greenway and recreation.On this basis,The concept,function,characteristics and elements of the greenway were analyzed.After that,the paper proposed that the urban recreational greenway.Urban recreation resources,make full use of urban ribbon space(such as roads,ribbon green,water corridors,historical blocks,etc.),so that the city recreation green road environmental protection,recreation,traffic and other functions to be effective play.Finally,this paper integrates the knowledge of multidisciplinary knowledge,establishes the method foundation and related technology of urban recreational greenway route selection,adopts the principal component analysis method and AHP hierarchy analysis method to establish the index evaluation system,and combines it with GIS technology to apply it to Harbin City of the city of the empirical study.Based on the relevant policies and planning documents of the main urban area of Harbin,this paper extracts the relevant information and data of natural,historical and humanities within the scope of the study,and summarizes the recreational resources and linear connection resources.Then,the evaluation system was used to evaluate the linear connection resources and recreational resources in the main urban area,and the evaluation results were introduced into the GIS to carry out the suitability analysis.Based on the analysis results,the selection of the urban recreational greenway line was completed.Harbin City,the main city of the recreational green road selection line,combined with the status of urban planning and construction,natural texture and spatial characteristics of the selected line layout and optimization for other cities of the recreational green road selection to provide some reference value.
